Bronco Sport Nabs Top Pick + Rating on IIHSMy background is IT architecture and software development so I understand root cause analysis, irreversible corrective actions, etc.
I don't believe anyone has detailed accident parameters such as exact speed and angle - just estimates based on the damage after the fact. The exact angle, speed, weight and height of the 2 vehicles can vary greatly and we've seen that even small changes in angle, speed or vehicle size and weight can make a dramatic change in results. At some point changes made to pass one test could reduce performance on other tests. You also have to consider impacts to cost and performance.
If we had data that says this type of test represents X fatal accidents every year then it would be easier but there are simply too many variables and not enough actual data to say that. And the only way to even guess at the effectiveness of a new crash test is to implement it and wait years and years and look at the overall death rate. But even then there are too many other variables to say for sure whether it was effective or not.
We'll never get to zero deaths so we have to find a balance where things are as safe as we can reasonably make them. I'm not willing to drive 35 mph everywhere or drive a tank just to reduce an already low death rate. Right now the IIHS gets all the benefit but incurs none of the cost of added testing.Wed, 05 May 2021 15:06:57 +0000
